Tires

Hey, figured you fellas would know a good tire suggestion! I was reading up
on the Pirelli Sport Demon tires, and they looked like they got excellent
reviews. What would you guys suggest? I ride quite a bit in 50 degree
weather, so I'm looking for something that doesn't require it to be hot out
to get good grip :D. My 95' GPZ has the ORIGINAL tires on it, so they gotta
go before I start riding it!!!
